Confusion with recording inter-app plugins?

Post by NoTech » Tue Jun 30, 2020 8:06 am

Hello,

I recently downloaded a really nice sounding keyboard app (Pure Synth Platinum) from the Apple App Store, onto my iPad.
I tried in different ways to get it to play and record as an inter-app instrument (non-MIDI?) on a channel in MTS on my iPad. So far I have only been able to get the icon into the effect strip, and open it up. I hear the audio from the PSP app in my headphones but for the life of me, I can’t get any sound into an MTS channel when I double-tap ‘play’ or hit record. No meter readings, nothing. I have gotten it in as a MIDI source but obv. that leaves out the app’s effects. Also weird is that when I get the app’s icon into the effect window, MTS goes into ‘mic mode’ with my iPad’s mic’s taking sound and monitoring. I cannot figure out how to play and record the app, via inter-app audio.

Lastly, after consulting the MTS iPad app’s manual a few times and reading about how the first choice is Audio Unit (which I guess is the process I tried using above?) ..and secondly Audiobus, I rolled the dice (I accept responsibility here lol) and downloaded AUM instead of Audiobus, liking it’s newer, more in-depth features and layout, as well as thinking it’d work just as well, getting the app to marry MTS.. When I brought up AUM, it recognized Pure Synth Platinum.. but MTS nowhere to be found. 😩

I would like to perhaps use the larger version of PSP in MTS Pro on my MacBook Pro but I have concerns about buying the software (or any other plugins) and finding they aren’t compatible with MTS there, also.

Thoughts? Help? Thanks!

Looks like you have the AU in an audio track. You should add a MIDI track and put the AU in the track Instrument Slot (that's "the first effect" slot, it has yellow text).

Now you can play the AU using the MTS keyboard.

FWIW at the moment I'm using 2 instances of Pure Synth Platinum 2.4.6 audio units by a project done with MTS Studio. I didn't tested it as IAA, since Pure Synth AU works without issues on my iPad Pro and I'm in favour of AU. However, if needed I would use IAA, too. None of the synth I tested work as IAA when MTS Studio is the host. MTS Studio's IAA support seems to be completely broken.

What happens when it doesn't 'work'? Does it fail to load? Is there no sound?

I see you have Model D. Does that work as IAA? It does here.

There's no audio output for Model D. This is what happens for all IAA plugins.

Re: Confusion with recording inter-app plugins?

Post by Support » Sun Jul 05, 2020 9:14 pm

Interesting. And thanks for the report!

Your song is at 44.1 kHz samplerate, but the hardware is at 48 kHz. That's probably because the hardware samplerate is locked at 48 kHz on your iPad model. Looks like the IAA app refuses to work at 44.1 kHz.

Please try a 48 kHz song in MTS:
- go to Studio --> Preferences
- set "New song samplerate" to 48000
- use Song-->New Song to create a new song
- add a MIDI track and load Model D

Let me know if this works.

While at it, you can also try a Crudebytes AU at 48 kHz. I'd be surprised if the samplerate makes a difference for AU, but you never know.

Model D IAA works A = 440 Hz, it's not detuned, playable by MTS Studio's keyboard, no reloading required
Oriental Strings AU does not work
iSymphonic IAA semi-works A = 440 Hz, also not detuned, works sometimes, needs reloading

Loading the 44.1 KHz song when connected to an USB audio interface, the Model D works, after disconnecting the USB audio interface, it still works. It's in tune, but audio suffers from glitches. I closed MTS Studio and Model D and restarted MTS Studio without the USB audio device attached. There's no audio output from the Model D anymore.

Re: Confusion with recording inter-app plugins?

Post by Ralf » Mon Jul 06, 2020 1:52 pm

I noticed that I already tested Oriental Strings IAA with a 48 KHz song before you mentioned it. I made a new 48 KHz song and Oriental Strings IAA failed, iSynphonic IAA failed, too. Model D IAA does play, but with glitches. IAA doesn't work, even if the sample rate does match.

Model D AU works correctly, no glitches, A = 440 Hz.

Using some hosts on the iPad Pro there are tuning issues with some synths. IIRC Model D is one of them. While I'm in favour of 48 KHz, I tend to use 44.1 KHz, since this sample rate usually does cause no or at least less issues, at least when connected to an USB audio interface. Without an USB audio interface there are more issues when using Cubasis or Auria Pro and obviously MTS Studio, too. However, those hosts suffer from similar, but not necessarily always the same issues.

Is there another iPad available with the resources of the 3rd gen iPad Pro, that doesn't cause such issues? My iPad 2 didn't cause such issues, but it wasn't usable for serious productions, due to the limited resources.

I made a heavy DSP load audio production with Auria Pro, that keeps up with audio productions made on a desktop PC, excepted that I was forced to chose 44.1 KHz, instead of 48 KHz. This is impossible with the iPad 2.

Now that I test MTS Studio, I suffer from more issues related to usable synth plugins, than I did when using Cubasis or Auria Pro.

FWIW at least until now, I didn't experience any issue with AU effects, when using MTS Studio.

Re: Confusion with recording inter-app plugins?

Recent iPad models (including yours) internally work at 48 kHz if the built-in speakers are used. IAA apps can only work at this internal samplerate, even if the MTS song uses 44.1 kHz. MTS currently doesn't treat this well, I'll look into improving this.

Interestingly, most if not all of these iPad models switch to 44.1 kHz when a 4 pin headphone jack is connected. The 4th pin is the mic input. If you're using headphone instead of the internal speakers this could actually be a nice workaround.

Just that the iPad Pro (12.9-inch) (3rd generation), Model MTFR2FD/A A1876, doesn't has a headphone jack at all ;).
